Tennessee Geological Survey

The mission of the Tennessee Geological Survey is to encourage and promote the prudent development and conservation of Tennessee’s geological, energy, and mineral resources by developing and maintaining data bases, maps and technical services; providing accurate geologic hazard assessments; and disseminating geologic information through publications and educational outreach activities.

The Tennessee Geological Survey is the lineal descendant of the first Tennessee Geological Survey that was established in 1831. It is thus one of the oldest geologic service and research organizations in the country. The survey advises other state agencies and federal and local organizations on matters relating to Tennessee geology.

Geology Programs

The Survey’s Nashville office covers Middle and West Tennessee. It is organized into mapping, subsurface geology, technical support, and West Tennessee. A regional office in Knoxville serves East Tennessee.

Maps & Publications

The Survey conducts research on the geology and mineral resources of Tennessee and makes the resulting scientific and technical information available to the public through the maps and publications.

Tennessee's Mineral Industry

Tennessee has a history of mining more different kinds of mineral resources than any other state east of the Mississippi River except North Carolina, dating back to the late 18th century.
